This patch converts libm function implementations in math/ from using weak_alias to using libm_alias_float to define public function names, in cases where it would be appropriate to define _Float32 aliases for those functions as well. expf and exp2f are omitted from this patch, given the in-progress patches that would change their symbol versioning arrangements (at a later stage it will be necessary to add macros that can be used for functions with such symbol versioning arrangements - which will apply to lgammaf as well - but for the initial patches in this area I'm just dealing with easy cases, and any symbol versioning changes to these functions while the work is in progress can effectively just undo the libm_alias_* changes as regards those functions). Tested for x86_64. Also tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * math/s_fmaf.c: Include <libm-alias-float.h>.
